Nut-lock



UNITED STATES WILLIAM o. ALTHEN,

PATENT Orric OF COLUMBUS, OI-IIO.

NUT-LOCK.

SPECIFICATION forming part of Letters Patent No. 599,980, dated March 1,1898.

Application filed March 22, 1 8 9 '7.

To aZZ whom it may concern:

Be it known that I, WILLIAM C. ALTHEN, a citizen of the United States,residing at C0- lumbus, in the county of Franklin and State of Ohio,have invented a certain new and useful Improvement in Nut-Locks, ofwhich the following is a specification.

My invention relates to the improvement of nut-locks, and has particularrelation to the improvement of that class of nut-locks shown anddescribed in my former letters Patent No. 578,591, dated March 9, 1897.

The object of my present invention is to combine with a nut-lock of theclass mentioned superior and improved means for retainin g the locking-disk against voluntary rotation and in desirable engagement with theend of the spindle of the vehicle 011 which the nut-lock is adapted foruse. This object I accomplish in the manner illustrated in theaccompanying drawings, in which Figure 1 is a longitudinal section of aportion of a wagon-spindle having my improved nut-lock in connectiontherewith. Fig. 2 is an end view of the spindle, showing the nutlockthereon. Fig. 3 is a side'elevation of the locking-disk which I employ,as hereinafter described. Fig. 4 is a view taken from the opposite sidefrom that shown in Fig. 3. Fig. 5 is an inner face View of thelockingdisk; and Fig. 6 is a detail view in elevation of the outer endportion of the spindle, showing the locking-disk in engagementtherewith, the adjoining and other parts being removed for the sake ofclearness in illustration.

Similar letters refer to similar parts throughout the several views.

(1 represents a vehicle-spindle, the threaded outer end portion of whichis adapted to receive a nut a in the usual manner. This outer end of thespindle is provided with a cross-recess a preferably of that characterwhich is ordinarily produced by a chisel or other similar sharpenedtool.

1) represents one of the parts of my improved lock which is in the formof a disk and which is provided with a continuous peripheral groove 1).The forward face and upper side of the disk I) has formed therein ashort way or channel a, which leads into the groove Z), while a similarway or channel dis formed in the lower side of the disk I) and SerialNo. 628,698. (No model.)

also communicates with the groove 1). Adjacent to the opening cl thegroove or channel b is provided in its inner wall with a recess e.Adjacent to the opening 0 the inner wall of the groove Z) is providedwith a shoulder 6. As indicated in the drawings, the inner line or wallof the groove 1) extends to the recess (2 in a slightly-inclineddirection.

The inner end or face of the disk I) has formed thereon,as shown moreclearly in Figs. 5 and 6 of the drawings, an outwardly-projecting rib 6which crosses said disk-face and intersects the central opening 6therein. This projecting rib, as shown more clearly in Fig. 6 ofthe'drawings, preferably has its sides inclined or formed flaring.

Through the central opening of the disk I) is adapted to pass the usualaxle lag-screw f, the head of the latter bearing against the outer faceof the disk I) and retaining said disk against the end of theaxle-spindle. In this position the recess or groove (1 of said spindleis adapted to receive the projecting rib e of the disk.

g represents a locking-ring the inner surface of which is provided, asindicated more clearly in Fig. 2 of the drawings, withoppositely-located inwardly-projecting lugs g This ring 9 is, asindicated in the drawings, adapted to embrace the disk I), the lugs gand g gaining entrance to the groove I) through the medium of the ways 0and d. The lugs having thus been made to enter the (llSl=-%5' groove 1)the locking-ring is turned,:$iownward, thelugs g and g traveling in thegroove b until the lug 9 drops into the recess 6 on the under side ofthe disk and the lug g is against the shoulder e of the upper side ofthe disk.

As indicated in the drawings, I preferably provide the ring g on oneside, which becomes the lower side when said ring is in the lockedposition, with a stem h, which serves partly as a weight to retain thering in a locked position and indicates to the eye whether or not saidring is in a locked position.

On the inner face of the ring 9 and in the upper portion thereof I haveprovided a forwardlyprojecting boss or lug it, which is adapted to comeinto contact with the outer face of the nut to in case the latter isscrewed inward past the outer-end of the spindle.

While the construction shown in my said former patent ordinarilyoperates to prevent any possible rotation of the disk against theaxle-spindle, it is evident that by providing the disk with thecross-rib e and providing the spindle with the receiving-recess a anytendency toward such voluntary rotation is entirely obviated, and theposition of the disk with reference to the axle-spindle is assured.

From the construction and operation which I have described it is obviousthat a simple, efiective, and inexpensive nut-lock is provided which maybe employed in connection with any of the ordinary constructions ofwagons. It is also evident that by the use of my improved locking deviceany tendency of the nut toward working off the spindle is obviated andthat said nut must retain its place on the spindle until the ring g isinverted and detached from the disk 1).

Having now fully described my invention, what I claim, and desire tosecure by Letters Patent, is

1. In a nut-lock the combination with a spindle having an end groove orrecess a formed therein, a nut adapted to screw on said spindle, and adisk secured against the end of said spindle, the body of said diskbeing out of contact with said nut, said disk having a projecting ribadapted to enter said spindlerecess, of a lag-screw passing over saiddisk and entering said spindle, substantially as and for the purposespecified. V

2. In a nut-lock the combination with a spindle havinga cross end recessa formed therein and a nut adapted to be screwed on said spindle, of alocking-disk secured against the end of said spindle, said locking-diskhaving a projecting rib adapted to enter said spindle end groove, aperipheral groove in said disk and oppositely-located ways leading tosaid groove and a ring 9 having oppositely-located lugs, the latterbeing adapted to enter said disk-groove through the medium of said ways,substantially as and for the purpose specified.
